INTRODUCTION

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources. Examples of suchmultiple-access technologies include code division multiple access(CDMA) systems, time division multiple access (TDMA) systems, frequencydivision multiple access (FDMA) systems, orthogonal frequency divisionmultiple access (OFDMA) systems, single-carrier frequency divisionmultiple access (SC-FDMA) systems, and time division synchronous codedivision multiple access (TD-SCDMA) systems.

These multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless devices to communicate on a municipal, national,regional, and even global level. An example telecommunication standardis 5G New Radio (NR). 5G NR is part of a continuous mobile broadbandevolution promulgated by Third Generation Partnership Project (3GPP) tomeet new requirements associated with latency, reliability, security,scalability (e.g., with Internet of Things (IoT)), and otherrequirements. 5G NR includes services associated with enhanced mobilebroadband (eMBB), massive machine type communications (mMTC), andultra-reliable low latency communications (URLLC). Some aspects of 5G NRmay be based on the 4G Long Term Evolution (LTE) standard. There existsa need for further improvements in 5G NR technology. These improvementsmay also be applicable to other multi-access technologies and thetelecommunication standards that employ these technologies.

The detailed description set forth below in connection with the appendeddrawings is intended as a description of various configurations and isnot intended to represent the only configurations in which the conceptsdescribed herein may be practiced. The detailed description includesspecific details for the purpose of providing a thorough understandingof various concepts. However, it will be apparent to those skilled inthe art that these concepts may be practiced without these specificdetails. In some instances, well known structures and components areshown in block diagram form in order to avoid obscuring such concepts.

Several aspects of telecommunication systems will now be presented withreference to various apparatus and methods. These apparatus and methodswill be described in the following detailed description and illustratedin the accompanying drawings by various blocks, components, circuits,processes, algorithms, etc. (collectively referred to as “elements”).These elements may be implemented using electronic hardware, computersoftware, or any combination thereof. Whether such elements areimplemented as hardware or software depends upon the particularapplication and design constraints imposed on the overall system.

By way of example, an element, or any portion of an element, or anycombination of elements may be implemented as a “processing system” thatincludes one or more processors. Examples of processors includemicroprocessors, microcontrollers, graphics processing units (GPUs),central processing units (CPUs), application processors, digital signalprocessors (DSPs), reduced instruction set computing (RISC) processors,systems on a chip (SoC), baseband processors, field programmable gatearrays (FPGAs), programmable logic devices (PLDs), state machines, gatedlogic, discrete hardware circuits, and other suitable hardwareconfigured to perform the various functionality described throughoutthis disclosure. One or more processors in the processing system mayexecute software. Software shall be construed broadly to meaninstructions, instruction sets, code, code segments, program code,programs, subprograms, software components, applications, softwareapplications, software packages, routines, subroutines, objects,executables, threads of execution, procedures, functions, etc., whetherreferred to as software, firmware, middleware, microcode, hardwaredescription language, or otherwise.

Accordingly, in one or more example embodiments, the functions describedmay be implemented in hardware, software, or any combination thereof. Ifimplemented in software, the functions may be stored on or encoded asone or more instructions or code on a computer-readable medium.Computer-readable media includes computer storage media. Storage mediamay be any available media that can be accessed by a computer. By way ofexample, and not limitation, such computer-readable media can comprise arandom-access memory (RAM), a read-only memory (ROM), an electricallyerasable programmable ROM (EEPROM), optical disk storage, magnetic diskstorage, other magnetic storage devices, combinations of the types ofcomputer-readable media, or any other medium that can be used to storecomputer executable code in the form of instructions or data structuresthat can be accessed by a computer.

While aspects and implementations are described in this application byillustration to some examples, those skilled in the art will understandthat additional implementations and use cases may come about in manydifferent arrangements and scenarios. Innovations described herein maybe implemented across many differing platform types, devices, systems,shapes, sizes, and packaging arrangements. For example, implementationsand/or uses may come about via integrated chip implementations and othernon-module-component based devices (e.g., end-user devices, vehicles,communication devices, computing devices, industrial equipment,retail/purchasing devices, medical devices, artificial intelligence(AI)-enabled devices, etc.). While some examples may or may not bespecifically directed to use cases or applications, a wide assortment ofapplicability of described innovations may occur. Implementations mayrange a spectrum from chip-level or modular components to non-modular,non-chip-level implementations and further to aggregate, distributed, ororiginal equipment manufacturer (OEM) devices or systems incorporatingone or more aspects of the described innovations. In some practicalsettings, devices incorporating described aspects and features may alsoinclude additional components and features for implementation andpractice of claimed and described aspect. For example, transmission andreception of wireless signals necessarily includes a number ofcomponents for analog and digital purposes (e.g., hardware componentsincluding antenna, RF-chains, power amplifiers, modulators, buffer,processor(s), interleaver, adders/summers, etc.). It is intended thatinnovations described herein may be practiced in a wide variety ofdevices, chip-level components, systems, distributed arrangements,aggregated or disaggregated components, end-user devices, etc. ofvarying sizes, shapes, and constitution.

FIG. 1 is a diagram illustrating an example of a wireless communicationssystem and an access network 100. The wireless communications system(also referred to as a wireless wide area network (WWAN)) includes basestations 102, UEs 104, an Evolved Packet Core (EPC) 160, and anothercore network 190 (e.g., a 5G Core (5GC)). The base stations 102 mayinclude macrocells (high power cellular base station) and/or small cells(low power cellular base station). The macrocells include base stations.The small cells include femtocells, picocells, and microcells.

The base stations 102 configured for 4G LTE (collectively referred to asEvolved Universal Mobile Telecommunications System (UMTS) TerrestrialRadio Access Network (E-UTRAN)) may interface with the EPC 160 throughfirst backhaul links 132 (e.g., S1 interface). The base stations 102configured for 5G NR (collectively referred to as Next Generation RAN(NG-RAN)) may interface with core network 190 through second backhaullinks 184. In addition to other functions, the base stations 102 mayperform one or more of the following functions: transfer of user data,radio channel ciphering and deciphering, integrity protection, headercompression, mobility control functions (e.g., handover, dualconnectivity), inter-cell interference coordination, connection setupand release, load balancing, distribution for non-access stratum (NAS)messages, NAS node selection, synchronization, radio access network(RAN) sharing, multimedia broadcast multicast service (MBMS), subscriberand equipment trace, RAN information management (RIM), paging,positioning, and delivery of warning messages. The base stations 102 maycommunicate directly or indirectly (e.g., through the EPC 160 or corenetwork 190) with each other over third backhaul links 134 (e.g., X2interface). The first backhaul links 132, the second backhaul links 184,and the third backhaul links 134 may be wired or wireless.

The base stations 102 may wirelessly communicate with the UEs 104. Eachof the base stations 102 may provide communication coverage for arespective geographic coverage area 110. There may be overlappinggeographic coverage areas 110. For example, the small cell 102′ may havea coverage area 110′ that overlaps the coverage area 110 of one or moremacro base stations 102. A network that includes both small cell andmacrocells may be known as a heterogeneous network. A heterogeneousnetwork may also include Home Evolved Node Bs (eNBs) (HeNBs), which mayprovide service to a restricted group known as a closed subscriber group(CSG). The communication links 120 between the base stations 102 and theUEs 104 may include uplink (UL) (also referred to as reverse link)transmissions from a UE 104 to a base station 102 and/or downlink (DL)(also referred to as forward link) transmissions from a base station 102to a UE 104. The communication links 120 may use multiple-input andmultiple-output (MIMO) antenna technology, including spatialmultiplexing, beamforming, and/or transmit diversity. The communicationlinks may be through one or more carriers. The base stations 102/UEs 104may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz)bandwidth per carrier allocated in a carrier aggregation of up to atotal of Yx MHz (x component carriers) used for transmission in eachdirection. The carriers may or may not be adjacent to each other.Allocation of carriers may be asymmetric with respect to DL and UL(e.g., more or fewer carriers may be allocated for DL than for UL). Thecomponent carriers may include a primary component carrier and one ormore secondary component carriers. A primary component carrier may bereferred to as a primary cell (PCell) and a secondary component carriermay be referred to as a secondary cell (SCell).

Certain UEs 104 may communicate with each other using device-to-device(D2D) communication link 158. The D2D communication link 158 may use theDL/UL WWAN spectrum. The D2D communication link 158 may use one or moresidelink channels, such as a physical sidelink broadcast channel(PSBCH), a physical sidelink discovery channel (PSDCH), a physicalsidelink shared channel (PSSCH), and a physical sidelink control channel(PSCCH). D2D communication may be through a variety of wireless D2Dcommunications systems, such as for example, WiMedia, Bluetooth, ZigBee,Wi-Fi based on the Institute of Electrical and Electronics Engineers(IEEE) 802.11 standard, LTE, or NR.

The wireless communications system may further include a Wi-Fi accesspoint (AP) 150 in communication with Wi-Fi stations (STAs) 152 viacommunication links 154, e.g., in a 5 GHz unlicensed frequency spectrumor the like. When communicating in an unlicensed frequency spectrum, theSTAs 152/AP 150 may perform a clear channel assessment (CCA) prior tocommunicating in order to determine whether the channel is available.

The small cell 102′ may operate in a licensed and/or an unlicensedfrequency spectrum. When operating in an unlicensed frequency spectrum,the small cell 102′ may employ NR and use the same unlicensed frequencyspectrum (e.g., 5 GHz, or the like) as used by the Wi-Fi AP 150. Thesmall cell 102′, employing NR in an unlicensed frequency spectrum, mayboost coverage to and/or increase capacity of the access network.

The electromagnetic spectrum is often subdivided, based onfrequency/wavelength, into various classes, bands, channels, etc. In 5GNR, two initial operating bands have been identified as frequency rangedesignations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz).Although a portion of FR1 is greater than 6 GHz, FR1 is often referredto (interchangeably) as a “sub-6 GHz” band in various documents andarticles. A similar nomenclature issue sometimes occurs with regard toFR2, which is often referred to (interchangeably) as a “millimeter wave”band in documents and articles, despite being different from theextremely high frequency (EHF) band (30 GHz-300 GHz) which is identifiedby the International Telecommunications Union (ITU) as a “millimeterwave” band.

The frequencies between FR1 and FR2 are often referred to as mid-bandfrequencies. Recent 5G NR studies have identified an operating band forthese mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1characteristics and/or FR2 characteristics, and thus may effectivelyextend features of FR1 and/or FR2 into mid-band frequencies. Inaddition, higher frequency bands are currently being explored to extend5G NR operation beyond 52.6 GHz. For example, three higher operatingbands have been identified as frequency range designations FR4a or FR4-1(52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

With the above aspects in mind, unless specifically stated otherwise, itshould be understood that the term “sub-6 GHz” or the like if usedherein may broadly represent frequencies that may be less than 6 GHz,may be within FR1, or may include mid-band frequencies. Further, unlessspecifically stated otherwise, it should be understood that the term“millimeter wave” or the like if used herein may broadly representfrequencies that may include mid-band frequencies, may be within FR2,FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band.

A base station 102, whether a small cell 102′ or a large cell (e.g.,macro base station), may include and/or be referred to as an eNB, gNodeB(gNB), or another type of base station. Some base stations, such as gNB180 may operate in a traditional sub 6 GHz spectrum, in millimeter wavefrequencies, and/or near millimeter wave frequencies in communicationwith the UE 104. When the gNB 180 operates in millimeter wave or nearmillimeter wave frequencies, the gNB 180 may be referred to as amillimeter wave base station. The millimeter wave base station 180 mayutilize beamforming 182 with the UE 104 to compensate for the path lossand short range. The base station 180 and the UE 104 may each include aplurality of antennas, such as antenna elements, antenna panels, and/orantenna arrays to facilitate the beamforming.

The base station 180 may transmit a beamformed signal to the UE 104 inone or more transmit directions 182′. The UE 104 may receive thebeamformed signal from the base station 180 in one or more receivedirections 182″. The UE 104 may also transmit a beamformed signal to thebase station 180 in one or more transmit directions. The base station180 may receive the beamformed signal from the UE 104 in one or morereceive directions. The base station 180/UE 104 may perform beamtraining to determine the best receive and transmit directions for eachof the base station 180/UE 104. The transmit and receive directions forthe base station 180 may or may not be the same. The transmit andreceive directions for the UE 104 may or may not be the same.

The EPC 160 may include a Mobility Management Entity (MME) 162, otherMMEs 164, a Serving Gateway 166, a Multimedia Broadcast MulticastService (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC)170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be incommunication with a Home Subscriber Server (HSS) 174. The MME 162 isthe control node that processes the signaling between the UEs 104 andthe EPC 160. Generally, the MME 162 provides bearer and connectionmanagement. All user Internet protocol (IP) packets are transferredthrough the Serving Gateway 166, which itself is connected to the PDNGateway 172. The PDN Gateway 172 provides UE IP address allocation aswell as other functions. The PDN Gateway 172 and the BM-SC 170 areconnected to the IP Services 176. The IP Services 176 may include theInternet, an intranet, an IP Multimedia Subsystem (IMS), a PS StreamingService, and/or other IP services. The BM-SC 170 may provide functionsfor MBMS user service provisioning and delivery. The BM-SC 170 may serveas an entry point for content provider MBMS transmission, may be used toauthorize and initiate MBMS Bearer Services within a public land mobilenetwork (PLMN), and may be used to schedule MBMS transmissions. The MBMSGateway 168 may be used to distribute MBMS traffic to the base stations102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN)area broadcasting a particular service, and may be responsible forsession management (start/stop) and for collecting eMBMS relatedcharging information.

The core network 190 may include an Access and Mobility ManagementFunction (AMF) 192, other AMFs 193, a Session Management Function (SMF)194, and a User Plane Function (UPF) 195. The AMF 192 may be incommunication with a Unified Data Management (UDM) 196. The AMF 192 isthe control node that processes the signaling between the UEs 104 andthe core network 190. Generally, the AMF 192 provides QoS flow andsession management. All user Internet protocol (IP) packets aretransferred through the UPF 195. The UPF 195 provides UE IP addressallocation as well as other functions. The UPF 195 is connected to theIP Services 197. The IP Services 197 may include the Internet, anintranet, an IP Multimedia Subsystem (IMS), a Packet Switch (PS)Streaming (PSS) Service, and/or other IP services.

The base station may include and/or be referred to as a gNB, Node B,eNB, an access point, a base transceiver station, a radio base station,a radio transceiver, a transceiver function, a basic service set (BSS),an extended service set (ESS), a transmit reception point (TRP), or someother suitable terminology. The base station 102 provides an accesspoint to the EPC 160 or core network 190 for a UE 104. Examples of UEs104 include a cellular phone, a smart phone, a session initiationprotocol (SIP) phone, a laptop, a personal digital assistant (PDA), asatellite radio, a global positioning system, a multimedia device, avideo device, a digital audio player (e.g., MP3 player), a camera, agame console, a tablet, a smart device, a wearable device, a vehicle, anelectric meter, a gas pump, a large or small kitchen appliance, ahealthcare device, an implant, a sensor/actuator, a display, or anyother similar functioning device. Some of the UEs 104 may be referred toas IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heartmonitor, etc.). The UE 104 may also be referred to as a station, amobile station, a subscriber station, a mobile unit, a subscriber unit,a wireless unit, a remote unit, a mobile device, a wireless device, awireless communications device, a remote device, a mobile subscriberstation, an access terminal, a mobile terminal, a wireless terminal, aremote terminal, a handset, a user agent, a mobile client, a client, orsome other suitable terminology. In some scenarios, the term UE may alsoapply to one or more companion devices such as in a device constellationarrangement. One or more of these devices may collectively access thenetwork and/or individually access the network.

Referring again to FIG. 1, in certain aspects, the UE 104 may beconfigured to generate a feedback codebook for a delayed PUCCHtransmission for a future valid occasion. For example, the UE 104 maycomprise a codebook component 198 configured to generate a feedbackcodebook including a first UCI and a second UCI. The UE 104 maydetermine that a scheduled transmission of a first UCI in a first PUCCHis within a first slot. The scheduled transmission is cancelled. The UE104 may configure a second UCI in a second PUCCH within a second slotsubsequent to the first slot. The UE 104 may generate a feedbackcodebook including the second UCI and the first UCI. The UE 104 maytransmit the feedback codebook in the second PUCCH within the secondslot.

Although the following description may be focused on 5G NR, the conceptsdescribed herein may be applicable to other similar areas, such as LTE,LTE-A, CDMA, GSM, and other wireless technologies.

FIG. 2A is a diagram 200 illustrating an example of a first subframewithin a 5G NR frame structure. FIG. 2B is a diagram 230 illustrating anexample of DL channels within a 5G NR subframe. FIG. 2C is a diagram 250illustrating an example of a second subframe within a 5G NR framestructure. FIG. 2D is a diagram 280 illustrating an example of ULchannels within a 5G NR subframe. The 5G NR frame structure may befrequency division duplexed (FDD) in which for a particular set ofsubcarriers (carrier system bandwidth), subframes within the set ofsubcarriers are dedicated for either DL or UL, or may be time divisionduplexed (TDD) in which for a particular set of subcarriers (carriersystem bandwidth), subframes within the set of subcarriers are dedicatedfor both DL and UL. In the examples provided by FIGS. 2A, 2C, the 5G NRframe structure is assumed to be TDD, with subframe 4 being configuredwith slot format 28 (with mostly DL), where D is DL, U is UL, and F isflexible for use between DL/UL, and subframe 3 being configured withslot format 1 (with all UL). While subframes 3, 4 are shown with slotformats 1, 28, respectively, any particular subframe may be configuredwith any of the various available slot formats 0-61. Slot formats 0, 1are all DL, UL, respectively. Other slot formats 2-61 include a mix ofDL, UL, and flexible symbols. UEs are configured with the slot format(dynamically through DL control information (DCI), orsemi-statically/statically through radio resource control (RRC)signaling) through a received slot format indicator (SFI). Note that thedescription infra applies also to a 5G NR frame structure that is TDD.

FIGS. 2A-2D illustrate a frame structure, and the aspects of the presentdisclosure may be applicable to other wireless communicationtechnologies, which may have a different frame structure and/ordifferent channels. A frame (10 ms) may be divided into 10 equally sizedsubframes (1 ms). Each subframe may include one or more time slots.Subframes may also include mini-slots, which may include 7, 4, or 2symbols. Each slot may include 14 or 12 symbols, depending on whetherthe cyclic prefix (CP) is normal or extended. For normal CP, each slotmay include 14 symbols, and for extended CP, each slot may include 12symbols. The symbols on DL may be CP orthogonal frequency divisionmultiplexing (OFDM) (CP-OFDM) symbols. The symbols on UL may be CP-OFDMsymbols (for high throughput scenarios) or discrete Fourier transform(DFT) spread OFDM (DFT-s-OFDM) symbols (also referred to as singlecarrier frequency-division multiple access (SC-FDMA) symbols) (for powerlimited scenarios; limited to a single stream transmission). The numberof slots within a subframe is based on the CP and the numerology. Thenumerology defines the subcarrier spacing (SCS) and, effectively, thesymbol length/duration, which is equal to 1/SCS.

SCS μ Δf = 2^(μ) · 15 [kHz] Cyclic prefix 0 15 Normal 1 30 Normal 2 60Normal, Extended 3 120 Normal 4 240 Normal

For normal CP (14 symbols/slot), different numerologies μ 0 to 4 allowfor 1, 2, 4, 8, and 16 slots, respectively, per subframe. For extendedCP, the numerology 2 allows for 4 slots per subframe. Accordingly, fornormal CP and numerology μ, there are 14 symbols/slot and 2^(μ)slots/subframe. The subcarrier spacing may be equal to 2^(μ)*15 kHz,where μ is the numerology 0 to 4. As such, the numerology μ=0 has asubcarrier spacing of 15 kHz and the numerology μ=4 has a subcarrierspacing of 240 kHz. The symbol length/duration is inversely related tothe subcarrier spacing. FIGS. 2A-2D provide an example of normal CP with14 symbols per slot and numerology μ=2 with 4 slots per subframe. Theslot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and thesymbol duration is approximately 16.67 μs. Within a set of frames, theremay be one or more different bandwidth parts (BWPs) (see FIG. 2B) thatare frequency division multiplexed. Each BWP may have a particularnumerology and CP (normal or extended).

A resource grid may be used to represent the frame structure. Each timeslot includes a resource block (RB) (also referred to as physical RBs(PRBs)) that extends 12 consecutive subcarriers. The resource grid isdivided into multiple resource elements (REs). The number of bitscarried by each RE depends on the modulation scheme.

As illustrated in FIG. 2A, some of the REs carry reference (pilot)signals (RS) for the UE. The RS may include demodulation RS (DM-RS)(indicated as R for one particular configuration, but other DM-RSconfigurations are possible) and channel state information referencesignals (CSI-RS) for channel estimation at the UE. The RS may alsoinclude beam measurement RS (BRS), beam refinement RS (BRRS), and phasetracking RS (PT-RS).

FIG. 2B illustrates an example of various DL channels within a subframeof a frame. The physical downlink control channel (PDCCH) carries DCIwithin one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or16 CCEs), each CCE including six RE groups (REGs), each REG including 12consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP maybe referred to as a control resource set (CORESET). A UE is configuredto monitor PDCCH candidates in a PDCCH search space (e.g., common searchspace, UE-specific search space) during PDCCH monitoring occasions onthe CORESET, where the PDCCH candidates have different DCI formats anddifferent aggregation levels. Additional BWPs may be located at greaterand/or lower frequencies across the channel bandwidth. A primarysynchronization signal (PSS) may be within symbol 2 of particularsubframes of a frame. The PSS is used by a UE 104 to determinesubframe/symbol timing and a physical layer identity. A secondarysynchronization signal (SSS) may be within symbol 4 of particularsubframes of a frame. The SSS is used by a UE to determine a physicallayer cell identity group number and radio frame timing. Based on thephysical layer identity and the physical layer cell identity groupnumber, the UE can determine a physical cell identifier (PCI). Based onthe PCI, the UE can determine the locations of the DM-RS. The physicalbroadcast channel (PBCH), which carries a master information block(MIB), may be logically grouped with the PSS and SSS to form asynchronization signal (SS)/PBCH block (also referred to as SS block(SSB)). The MIB provides a number of RBs in the system bandwidth and asystem frame number (SFN). The physical downlink shared channel (PDSCH)carries user data, broadcast system information not transmitted throughthe PBCH such as system information blocks (SIBs), and paging messages.

As illustrated in FIG. 2C, some of the REs carry DM-RS (indicated as Rfor one particular configuration, but other DM-RS configurations arepossible) for channel estimation at the base station. The UE maytransmit DM-RS for the physical uplink control channel (PUCCH) and DM-RSfor the physical uplink shared channel (PUSCH). The PUSCH DM-RS may betransmitted in the first one or two symbols of the PUSCH. The PUCCHDM-RS may be transmitted in different configurations depending onwhether short or long PUCCHs are transmitted and depending on theparticular PUCCH format used. The UE may transmit sounding referencesignals (SRS). The SRS may be transmitted in the last symbol of asubframe. The SRS may have a comb structure, and a UE may transmit SRSon one of the combs. The SRS may be used by a base station for channelquality estimation to enable frequency-dependent scheduling on the UL.

FIG. 2D illustrates an example of various UL channels within a subframeof a frame. The PUCCH may be located as indicated in one configuration.The PUCCH carries uplink control information (UCI), such as schedulingrequests, a channel quality indicator (CQI), a precoding matrixindicator (PMI), a rank indicator (RI), and hybrid automatic repeatrequest (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one ormore HARQ ACK bits indicating one or more ACK and/or negative ACK(NACK)). The PUSCH carries data, and may additionally be used to carry abuffer status report (BSR), a power headroom report (PHR), and/or UCI.

FIG. 3 is a block diagram of a base station 310 in communication with aUE 350 in an access network. In the DL, IP packets from the EPC 160 maybe provided to a controller/processor 375. The controller/processor 375implements layer 3 and layer 2 functionality. Layer 3 includes a radioresource control (RRC) layer, and layer 2 includes a service dataadaptation protocol (SDAP) layer, a packet data convergence protocol(PDCP) layer, a radio link control (RLC) layer, and a medium accesscontrol (MAC) layer. The controller/processor 375 provides RRC layerfunctionality associated with broadcasting of system information (e.g.,MIB, SIBs), RRC connection control (e.g., RRC connection paging, RRCconnection establishment, RRC connection modification, and RRCconnection release), inter radio access technology (RAT) mobility, andmeasurement configuration for UE measurement reporting; PDCP layerfunctionality associated with header compression/decompression, security(ciphering, deciphering, integrity protection, integrity verification),and handover support functions; RLC layer functionality associated withthe transfer of upper layer packet data units (PDUs), error correctionthrough ARQ, concatenation, segmentation, and reassembly of RLC servicedata units (SDUs), re-segmentation of RLC data PDUs, and reordering ofRLC data PDUs; and MAC layer functionality associated with mappingbetween logical channels and transport channels, multiplexing of MACSDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs,scheduling information reporting, error correction through HARQ,priority handling, and logical channel prioritization.

The transmit (TX) processor 316 and the receive (RX) processor 370implement layer 1 functionality associated with various signalprocessing functions. Layer 1, which includes a physical (PHY) layer,may include error detection on the transport channels, forward errorcorrection (FEC) coding/decoding of the transport channels,interleaving, rate matching, mapping onto physical channels,modulation/demodulation of physical channels, and MIMO antennaprocessing. The TX processor 316 handles mapping to signalconstellations based on various modulation schemes (e.g., binaryphase-shift keying (BPSK), quadrature phase-shift keying (QPSK),M-phase-shift keying (M-PSK), M-quadrature amplitude modulation(M-QAM)). The coded and modulated symbols may then be split intoparallel streams. Each stream may then be mapped to an OFDM subcarrier,multiplexed with a reference signal (e.g., pilot) in the time and/orfrequency domain, and then combined together using an Inverse FastFourier Transform (IFFT) to produce a physical channel carrying a timedomain OFDM symbol stream. The OFDM stream is spatially precoded toproduce multiple spatial streams. Channel estimates from a channelestimator 374 may be used to determine the coding and modulation scheme,as well as for spatial processing. The channel estimate may be derivedfrom a reference signal and/or channel condition feedback transmitted bythe UE 350. Each spatial stream may then be provided to a differentantenna 320 via a separate transmitter 318 TX. Each transmitter 318 TXmay modulate a radio frequency (RF) carrier with a respective spatialstream for transmission.

At the UE 350, each receiver 354 RX receives a signal through itsrespective antenna 352. Each receiver 354 RX recovers informationmodulated onto an RF carrier and provides the information to the receive(RX) processor 356. The TX processor 368 and the RX processor 356implement layer 1 functionality associated with various signalprocessing functions. The RX processor 356 may perform spatialprocessing on the information to recover any spatial streams destinedfor the UE 350. If multiple spatial streams are destined for the UE 350,they may be combined by the RX processor 356 into a single OFDM symbolstream. The RX processor 356 then converts the OFDM symbol stream fromthe time-domain to the frequency domain using a Fast Fourier Transform(FFT). The frequency domain signal comprises a separate OFDM symbolstream for each subcarrier of the OFDM signal. The symbols on eachsubcarrier, and the reference signal, are recovered and demodulated bydetermining the most likely signal constellation points transmitted bythe base station 310. These soft decisions may be based on channelestimates computed by the channel estimator 358. The soft decisions arethen decoded and deinterleaved to recover the data and control signalsthat were originally transmitted by the base station 310 on the physicalchannel. The data and control signals are then provided to thecontroller/processor 359, which implements layer 3 and layer 2functionality.

The controller/processor 359 can be associated with a memory 360 thatstores program codes and data. The memory 360 may be referred to as acomputer-readable medium. In the UL, the controller/processor 359provides demultiplexing between transport and logical channels, packetreassembly, deciphering, header decompression, and control signalprocessing to recover IP packets from the EPC 160. Thecontroller/processor 359 is also responsible for error detection usingan ACK and/or NACK protocol to support HARQ operations.

Similar to the functionality described in connection with the DLtransmission by the base station 310, the controller/processor 359provides RRC layer functionality associated with system information(e.g., MIB, SIBs) acquisition, RRC connections, and measurementreporting; PDCP layer functionality associated with headercompression/decompression, and security (ciphering, deciphering,integrity protection, integrity verification); RLC layer functionalityassociated with the transfer of upper layer PDUs, error correctionthrough ARQ, concatenation, segmentation, and reassembly of RLC SDUs,re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; andMAC layer functionality associated with mapping between logical channelsand transport channels, multiplexing of MAC SDUs onto TBs,demultiplexing of MAC SDUs from TBs, scheduling information reporting,error correction through HARQ, priority handling, and logical channelprioritization.

Channel estimates derived by a channel estimator 358 from a referencesignal or feedback transmitted by the base station 310 may be used bythe TX processor 368 to select the appropriate coding and modulationschemes, and to facilitate spatial processing. The spatial streamsgenerated by the TX processor 368 may be provided to different antenna352 via separate transmitters 354TX. Each transmitter 354TX may modulatean RF carrier with a respective spatial stream for transmission.

The UL transmission is processed at the base station 310 in a mannersimilar to that described in connection with the receiver function atthe UE 350. Each receiver 318RX receives a signal through its respectiveantenna 320. Each receiver 318RX recovers information modulated onto anRF carrier and provides the information to a RX processor 370.

The controller/processor 375 can be associated with a memory 376 thatstores program codes and data. The memory 376 may be referred to as acomputer-readable medium. In the UL, the controller/processor 375provides demultiplexing between transport and logical channels, packetreassembly, deciphering, header decompression, control signal processingto recover IP packets from the UE 350. IP packets from thecontroller/processor 375 may be provided to the EPC 160. Thecontroller/processor 375 is also responsible for error detection usingan ACK and/or NACK protocol to support HARQ operations.

At least one of the TX processor 368, the RX processor 356, and thecontroller/processor 359 may be configured to perform aspects inconnection with 198 of FIG. 1.

In wireless communication systems, a UE may be configured with one ormore SPS configurations. For each SPS configuration, a HARQ-ACK feedbacktimeline (K1) may be given in a DCI format to activate the SPSconfiguration. If the field is not included in the DCI, K1 may beprovided by an RRC parameter (e.g., dl-DataToUL-ACK). The PUCCH resourceto be used for SPS PDSCH occasions of a given SPS configurations may bedetermined based on the activating DCI. For example, for a first PDSCHafter receipt of an activating DCI, the PUCCH resource may be determinedby a PUCCH resource indicator (PRI) in the activating DCI. For all otherPDSCH occasions, the PUCCH resource may be given by an RRC parameter(e.g., SPS-PUCCH-A/N). However, in some instances, for some SPSoccasions, K1 and/or dynamic/semi-static PRI may point to a PUCCHresource that is not valid for PUCCH transmissions.

For example, with reference to the example 400 of FIG. 4A, an SPSconfiguration with a periodicity of one slot is shown, and K1 is set to3 slots. The example 400 of FIG. 4A includes a plurality of DL slots 402and UL slots 404, where a PDSCH may be received in a DL slot 402, and aPUCCH slot may be transmitted in a UL slot 404. The example 400discloses that for the first PDSCH, the K1 406 points to a UL slot 404,such that the PUCCH resource carrying SPS for the first PDSCH configuredto be transmitted in the first UL slot 404. With regard to the secondPDSCH, the K1 408 points to a semi-static DL slot 402. The semi-staticDL slot 402 is not a valid slot to transmit a PUCCH. As such, the PUCCHtransmission for the second PDSCH is not compatible with the scheduledslot, and the HARQ-ACK may not be transmitted. Thus, the PUCCH resourcefor the SPS collides with the invalid symbol and will be dropped. Thisapproach may be costly for TDD bands where all the SPS PDSCHs for whichthe HARQ-ACK is dropped would have to be retransmitted. The samesituation may occur if K1 and PM point to a PUCCH resource which ispartially invalid for transmission, such as where some of the symbols ofthe PUCCH resource overlap with semi-static DL symbols and/or flexiblesymbols.

Aspects presented herein provide a configuration for codebook generatefor SPS with a delayed HARQ. For example, aspects presented herein mayallow a UE to generate a HARQ-ACK codebook for a delayed PUCCHtransmission for a future valid occasion. At least one advantage of thedisclosure is that in instances where the PUCCH resource for the SPScollides with an invalid symbol, instead of being dropped, the PUCCHtransmission may be delayed to a future valid occasion.

With reference to example 410 of FIG. 4B, which may be configured in amanner similar to FIG. 4A. The example 410 may have the SPSconfiguration with a periodicity of one slot, and a K1 set to 3 slots,similarly as in FIG. 4A. The example 410 discloses that for the firstPDSCH, the K1 406 points to a UL slot 404, such that the PUCCH resourcecarrying SPS for the first PDSCH configured to be transmitted in thefirst UL slot 404. With regard to the second PDSCH, the K1 408 points toa semi-static DL slot 402. The semi-static DL slot 402 is not a validslot to transmit a PUCCH carrying the HARQ-ACK. However, instead of theHARQ-ACK being dropped, the HARQ-ACK transmission may be delayed to afuture valid occasion, as shown at 412 of FIG. 4B, which may be thesecond UL slot 404. The UE may be configured to generate a HARQ-ACKcodebook for the delayed HARQ-ACK transmission.

In some aspects, the delayed PUCCH transmission may point to a slot thatcorresponds to another PDSCH. For example, as shown in FIG. 4B, the K1406 of the third PDSCH points to the second UL slot 404, which may alsoinclude the delayed HARQ-ACK transmission. In such aspects, the PUCCHresource may carry the SPS for the third PDSCH and the delayed HARQ-ACKtransmission.

A UE may receive an SPS configuration and if the UE reports a HARQ-ACKinformation in a PUCCH only for SPS PDSCH reception, then the UE may fixthe carrier c and the SPS configuration s on a carrier. The UE maygenerate a HARQ-ACK bit for each number of DL slots for PDSCH receptionwith HARQ-ACK information multiplexed on the PUCCH, which may run from 0to N_(c) ^(DL)−1, where N_(c) ^(DL) is the number of DL slots for SPSPDSCH reception on a serving cell c with HARQ-ACK informationmultiplexed on the PUCCH. The UE may loop over the DL slots, and thenover SPS configurations, and then over DL carriers.

The UE may generate the HARQ-ACK bits for the cancelled PUCCHtransmission, as if the PUCCH were not cancelled. The UE may then appendthe generated HARQ-ACK information to the new HARQ bit sequence in orderto generate a HARQ-ACK codebook for transmission. The generated HARQ-ACKcodebook may be transmitted in a second PUCCH within a second slot,wherein the second slot is subsequent the slot of the cancelled PUCCHtransmission. The UE may append the HARQ information bits for thecancelled PUCCH transmission in different manners. In some aspects, theHARQ information bits may be appended per carrier. For example, for eachcarrier, the old bits for all the SPS configurations may be appendedwith all the new bits for all the SPS configurations, and then move tothe next carrier. In another example, for each carrier, the new bits forall the SPS configurations may be appended with all the old bits for allthe SPS configurations, and then move to the next carrier. In someaspects, the UE may generate a new PUCCH HARQ sequence followed by theold PUCCH HARQ sequence. In some aspects, the old HARQ information maybe appended for each SPS configuration or carrier. For example, the oldHARQ information may be appended to an end of the new HARQ information.In such instances, the combination of the old and new HARQ informationmay comprise appending, for each serving cell c of a set of servingcells configured to the UE and for each SPS PDSCH configuration s of aset of SPS PDSCH configurations configured to the UE of the serving cellc, the old HARQ information for the serving cell c and the SPS PDSCHconfiguration s to an end of the new HARQ information for the servingcell c and the SPS PDSCH configuration s. In some aspects, the old HARQinformation may be appended to a beginning of the new HARQ information.For example, the combination of the old and new HARQ information maycomprise appending, for each serving cell c of a set of serving cellsconfigured to the UE and for each SPS PDSCH configuration s of a set ofSPS PDSCH configurations configured to the UE of the serving cell c, theold HARQ information for the serving cell c and the SPS PDSCHconfiguration s to a beginning of the new HARQ information for theserving cell c and the SPS PDSCH configuration s. In some aspects, theold HARQ information may be comprised of a plurality of old HARQinformation from different slots, where each of plurality of old HARQinformation corresponds to a delayed HARQ-ACK transmission. The old HARQinformation or the plurality of old HARQ information may be multiplexedwith the new HARQ information. In instances where the plurality of oldHARQ information is multiplexed with the new HARQ information, theplurality of old HARQ information may be multiplexed with the new HARQinformation in a slot n, wherein the ordering of the multiplexed HARQinformation may be based on a slot index. The slot index may correspondto the respective slot for each of the plurality of old HARQinformation. The combination of the old HARQ information and the newHARQ information may generate a HARQ-ACK codebook for transmission.

In some aspects, generating the HARQ-ACK codebook may comprisegenerating the HARQ-ACK codebook based on the DL slot for SPS PDSCHreception with HARQ-ACK information multiplexed on a first or cancelledPUCCH and with HARQ-ACK information multiplexed on a second orsubsequent PUCCH. In some aspects, generating the HARQ-ACK codebook maycomprise generating the HARQ-ACK codebook based on DL slots including afirst DL slot on which a first SPS PDSCH is received and a second DLslot on which a second SPS PDSCH is received. The HARQ-ACK codebook maybe based on HARQ-ACK information including the first or cancelledHARQ-ACK information associated with the first DL slot and the second orsubsequent HARQ-ACK information associated with the second DL slot. Insuch aspects, a new HARQ-ACK feedback timeline may be defined K1′,wherein K1′ is the original K1 plus an offset for the PDSCHs whoseHARQ-ACK is scheduled on the DL slot. The new K1′ may be utilized togenerate the HARQ-ACK codebook for such SPS PDSCHs.

FIG. 5 is a call flow diagram 500 of signaling between a UE 502 and abase station 504. The base station 504 may be configured to provide atleast one cell. The UE 502 may be configured to communicate with thebase station 504. For example, in the context of FIG. 1, the basestation 504 may correspond to base station 102/180 and, accordingly, thecell may include a geographic coverage area 110 in which communicationcoverage is provided and/or small cell 102′ having a coverage area 110′.Further, a UE 502 may correspond to at least UE 104. In another example,in the context of FIG. 3, the base station 504 may correspond to basestation 310 and the UE 502 may correspond to UE 350.

As illustrated at 508, the UE 502 may determine that a scheduledtransmission of a first UCI in a first PUCCH is within a first slot. Forexample, the UE 502 may determine that a scheduled transmission of firstHARQ-ACK information in a first PUCCH is within a first slot. The UE 502may determine that the scheduled transmission of the first UCI (e.g.,HARQ-ACK information) in the first PUCCH within the first slot includesinvalid symbols for the transmission, such that the scheduledtransmission is cancelled. The scheduled transmission may be cancelledbased on a collision with the invalid symbols. The UE may determine thescheduled transmission of the first UCI (e.g., HARQ-ACK information) inthe first PUCCH within the first slot in response to a received firstSPS PDSCH 506. The UE 502 may receive the first SPS PDSCH (e.g., SPSPDSCH 506) from the base station 504.

As illustrated at 510, the UE 502 may configure a second UCI in a secondPUCCH within a second slot. For example, the UE 502 may determine totransmit second HARQ-ACK information in a second PUCCH. The UE 502 maydetermine to transmit the second UCI (e.g., HARQ-ACK information) in thesecond PUCCH within a second slot subsequent to the first slot. The UE502 may configure the second UCI (e.g., HARQ-ACK information) in thesecond PUCCH in response to a received second SPS PDSCH (e.g., SPS PDSCH506).
